While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more
To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more

Shipping is consistently fast usually…
Shipping is consistently fast usually at my door within a couple days of ordering. What really sets them apart is the COAs. Every lot has current, verifiable third-party testing posted before you even buy. That level of transparency is rare in this space and it's the reason I keep coming back. Product quality has been spot on across multiple orders. Highly recommend for anyone who actually cares about knowing what they're getting.
